Salafist 'Sharia Police' patrols spark concern in Germany

German politicians and media Monday called for stricter laws against radical Islamist propaganda after a group of ultra-conservative Salafists took to the streets calling itself the "Sharia Police".

"No tolerance for Salafists" said conservative daily Die Welt after a small group of men, wearing orange vests with "Sharia Police" written on them, went on a series of "patrols" in the western city of Wuppertal.

Seeking to enforce their austere moral code, they told Friday night club-goers to refrain from drinking alcohol and listening to music and arcade customers not to play games for money.

A video circulating online shows among them Sven Lau, a German Salafist convert who claims to be one of those behind the patrol idea.

Under current German law, the self-styled "Sharia Police" could at most face a charge of disturbing public order.

No arrests have been made so far, but political leaders warned they would crack down on the Islamist patrol if it took its campaign any further.
